Ave B Free Jam is a live album by drummer Laurence Cook, trumpeters Jacques Coursil and Warren Gale, clarinetist Perry Robinson, and bassist Steve Tintweiss.

Consisting of a continuous, extended free improvisation, it was recorded on May 12, 1967, in New York City, and was issued on CD in 2021 by Inky Dot Media.

"[7] The Big Takeover's Michael Toland remarked: "The group keeps the pedal to the metal for most of the album... giving it all they've got in a nearly unbroken string of freeform self-expression.

"[4] In an article for Contemporary Fusion Reviews, Dick Metcalf wrote: "if you're an improvised music aficionado, this is one of the most important albums you will ever have... over an hour... of freestyle madness that will make your head spin lol... the recording is an improvisor's treasure and gets a MOST HIGHLY RECOMMENDED rating.

"[9] A reviewer for Take Effect called the album "an avant-garde experience you’re not going to hear anywhere else," and remarked: "it's amazing that this was recorded way back in 1967... and it clearly illustrates just how ahead of their time these musicians were.
